Apple to figure out your typing speed to improve autocorrect
This patent uses a timestamp on a string of typed characters which is then analyzed using a process in autocorrect or autocompletion. A "baseline typing speed" can be computed and if it takes longer to type a particular sentence, the delay could mean that there are misspelled words or other typing errors. Speed faster than the baseline could indicate the double strike of a letter by mistake. The application reads, "For example, if the string “theere” is entered and the time between the keystrokes “ee” is less than an associated baseline by more than a threshold amount, the replacement candidate “there” may be assigned a higher score."
The whole technology could be put into the Apple iPhone and start with a pre-determined typing speed that would be adjusted for the phone's actual user and if the user typed faster or slower than the typical user. Besides using speed to catch mistakes, the feature would also examine the location of the letters typed on the keyboard and the geometry of words spelled. words. The patent application reads, "For example, a word that is similar to the typed text except for one or more errors associated potentially with keyboard geometry, such as differing by a letter where the correct letter is located adjacent to the typed incorrect letter on the keyboard, may be suggested."
The third patent, No. 12/976864, also deals with trying to "tag" certain parts of written speech but limits the language processing to search queries. The patent application discusses a process for analyzing phrases of speech to make searching documents or the internet, more efficient. Some of Apple's autocorrect patents have been used in its lawsuits with Samsung. Back in February, Apple accused Samsung of infringing on a patent for a "Method, system, and graphical user interface for providing word recommendations".
